COMFOUND LNING HEAD.

Application iiled.. October 17, 1921. Serial No. 508,102.

The. present invention has to do with apparatus for and a process of lining the flanges of can ends, with compound gasket material, and relates more particularly to means for' applying such material tothe can ends in liquid form and in measured qua-ntities.

A principal object of the invention is. the provision of a process and an. efficient and commercially practicable apparatus for iirst withdrawing measured' charges of' material from a source' of supply and then. transferring said charges to'v distributi-ngY means adapted to maintain constant operative position with respect tothe can. end to be lined.

A further object of the inventiony is the provision of anl improved andv simplifiedy apparatus for the purpose ofevenly distributing gasket lining material in measured' quantities upon the flanges of can ends in certain 'manner andl with the use of a minimum number of operative'- parts.

Still another object of the invention is the provision' of al process for' lining the flanges of'can ends' and a structure for carrying out suoli process whereby the material may be positioned in accurate amount upon various parts of the can end flange and distributed in morel even fashion than has been found possible withL other processes and apparatus.

Another and highly important object of the invention is theI provision, in apparatus for the purposel stated, of an intermediate measuring member adapted to receive measured charges of material from a sourcel of supply and subsequently acting distributing means adapted to receive said charges and apply the same tothe can ends in particularly effective manner'.

A still further object of? theinvention is the provision of mechanisml for lining can ends in which the ends maybe Jfed into position to be lined, the lining material withdrawn in measured quantities from a source of supply and said measured quantities applied to the flanges of the can ends through the use of single power means and a minimum number of power transmitting members.

Numerous other obgects and advantages of the invention will' be apparentas it is' drawings, discloses a preferred embodiment thereof.

The can end. stack holder comprises a plurality of posts or upstandingl rods 16` and mechanism is provided therebeneath for singly selecting one of the canv ends17 from the bottom of the stack and transferring it to a can end support 18l positioned beneath the lining head. 12. This mechanism` comprises a slide 19 operating between guide-- ways 21 on the upper part of the table 11 and actuated by'a cam 22 through. anY armr 23, a lever 24 and a link connection 25. rl`he arm' 23 has a bifurcated end or yoke" 26: engaging an operating shaft 27 and carrying a. roller adapted to engage in a groove 28 in the cam 22 to operate the can end feed slide 19. rlhe arm 23 is adjustable by means of a threaded connection 29 and is pivoted at 31 onto the lever 2l which in' turn' is pivoted at 32 onto* av punctur'ed lug 33? eX- tending upwardly from the-base 15. It will be observed that in thismanner theendI feeding mechanismis operated. in timed relationship with respect to the lining head operating mechanism, and it ivill be understood that this part of the mechanism may be of any Well known or preferred form to accomplish the end just stated.

The lining head is supported upon the table 1l by a suitable bracket 34 and has therein a reservoir 35 adapted to contain a quantity of gasket lining material 36. An entrance pipe 37 for the lining material is provided in one side of a cover member 88, Which member has screw threaded engagement With the Wall 89 of the reservoir, and an air pipe 4l is provided at another point in the cover for admitting air to maintain a pressure in the reservoir. ln the bottom of the reservoir are openings 42 spaced at intervals and arranged, in the pre'ent instance, around a circular path and 45O apart. A gear 43 is arranged immediately beneath the bottom of the reservoir and has chambers 44 located therein in a manner corresponding to the arrangement of the apertures 42, with which said chambers are adapted to register at given points in the path of rotation of said gear. A body part 45 of the lining head is secured by pins 4o to the lower part of the reservoir and is cut away near the top at 47 to provide a bearing for the gear 43. Spaced about this body part in the same circular path in which the apertures 42 and the chambers 44 are arranged are distributing rollers 48 rotatably mounted on pins 49 having bearing in the body 45 and imn'iediately above these rollers are openings 5l adapted to register With the chambers 44 at given interva s in the rotation of the gear 43. The gear 43 is driven intermittently by a mutilated gear 52 having teeth 53 on a relatively small portion only of its periphery, this driving gear being mounted upon an auxiliary shaft 54.

AReferring novv to Fig. 3, it Will be noted that the drive shaft 27 carries a pulley by which it is driven, and also carries the cam 22 by which the cover feeding mechanism is operated, and gearing, to be noiv described through ivhich the lining head and the can end support are operated. A bevel gear is secured on the drive shaft near its bearing 5T in the frame 14 and is in constant mesh with a smaller bevel gear 58 carried on the lower end of the shaft 54. The relative size of these tivo gears is such that the shaft 54 turns tivice for every single revolution of the shaft 27, and the gear V52 has just enough teeth to move the gear 4S the necessary 45 to lirst move the chambers 44 from position in registration with the apertures 42 to registral ion ivith the openings 51, and to again establish con'iniuniration between one of the apertures 42 and the chambers 44 on the next subsequent revolution of the gear 52. It will thus be seen that the relative size of the gears 56 and 58 results in the measuring gear 43 coming to rest tivice and being moved twice during one cycle of operation.

Another bevel gear 59 is secured on the drive shaft 27 and meshes with a smaller bevel gear (il carried on the loiver end of a shaft 62 which is secured at the upper end thereof by a screiv threaded engagement at 63 to a can end support 18. The shaft 62 is reciprocable by means of a bell cranlr P4, one arm 65 of which has engagement With a. grooved collar 66, and the other arm 6?' of Which carries a roller 68 engaging in a cam groove 69 in a cam member 7l carried on the shaft 27. in this manner the can ends Which are successively fed onto the support 18 are lifted, after being so positioned, to the rollers 48 to have the gasket lining material distributed in the flange 72. it will be observed that the application of the material takes place at diiferent points in the periphery of the flange and the rotating of the end accomplishes even distribution entirely around the peripheral edge of the end. After being lined, the end is ejected in any suitable or usual manner and another is fed onto the support 1S in the manner hereinbefore described.

The shafts 62 and 54 are supported in bearing members 73 and have bearing at their upper ends in t-he table l1 in any preferred manner. A spring 74 is secured in a collar 75 extending through an aperture 7G in the lining head and exerts tension upon a rod 77 carrying a ball 78 adapted to contact with and to yieldingly resist upward movement of the can end 17,.

Vllith the mechanism just described, the lining material, which ordinarily is a compound of relatively thin liquid form, may be first completely Withdrawn in measured quantities from the source of supply and subsequently transferred by exact predetermined steps to the distributing means by which it is evenly applied about the can end flange. This results in rapid, accurate and economical lining of the ends Without any waste of material and precludes the poesibility of uneven distribution.

lt is thought that the invention and many of its attendant advantages Will loe understood from the foregoing description, and it ivill be apparent that various changes may be made in the form, construction and arrangement of the parts without departing from the spirit and scope ot the invention or sacrificing all of its material. advant'ic'e, the form hereinbefore described being m ly a preferred embodiment thereof.
